Toktogul reservoir with a storage capacity of 19.5 km³. It is part of Kyrgyzstan’s Naryn-Syr

Darya cascade, a system of reservoirs and dams (Toktogul, Kurpsai, Tashkumyr, Shamaldysai,

Uch-Kurgan) that regulates the flow of the Naryn River. In Tajikistan, nine operating

reservoirs with a total storage capacity of 29 km³ were built. The two biggest ones

are Nurek (10.5 km³) at the Vaksh River and Kairakum (4.16 km³) at the Syr Darya. The

Nurek dam is the highest dam in the world (300 m).

In order to compensate the two Soviet republics for their losses in arable land and

the costs of operation and maintenance of the facilities, a unified water-energy system

was established. The reservoirs were constructed and operated primarily for downstream

irrigation supply. Only at peak times was water released to produce electricity. In exchange

for water withdrawal in the growing period in spring and summer, the downstream states

delivered energy in the form of coal and gas in winter. This worked well, as both water

and energy were centrally allocated by the government in Moscow.

In the official water governance structure of the Soviet Union, all water resources

were controlled by the Union-wide Ministry of Melioration and Water Management

(MinVodKhoz). In Central Asia, initially a regional agency (SredAzVodKhoz) was responsible

for the whole Aral Sea Basin and also received orders from Moscow. Later, corresponding

ministries in the Soviet republics were established, but their responsibilities

were mainly restricted to the implementation of the decisions of the central MinVodKhoz

in Moscow. The agency pursued an integrated basin-wide water and energy management

approach in which each republic fulfilled a particular function. Water allocation was

standardized with fixed schedules for republics, provinces and districts. Basin management

administrations existed for some small rivers in Central Asia. However, they had

a hard time competing with the province administrations, securing water foremost for

the fulfilment of their own plans. The central MinVodKhoz itself had many subordinated

agencies with overlapping functions and competencies, resulting in inconsistencies and

ineffective implementation. It was responsible for planning, supplying, receiving, and

controlling, so that all of the relevant water management functions were combined in

one agency with minimal external oversight and control. The local water management

authorities were also restructured under Soviet rule. During collectivization, all of the

small land plots were combined into huge collective and state farms (kolkhoz and sovkhoz),

which were in charge of the on-farm irrigation systems. 7

The Soviet ideology of total human command over nature led to a belief in the

ability to exploit natural resources, including water resources, indefinitely. Apart from a

relatively low usage fee, water use was not paid for on a quantitative basis. This approach,

along with the unclear and competing distribution of competencies among different state

agencies, led to an erosion of the local sense of responsibility and a pattern of usage that

disregarded the interests of others. The old norms and rules that ensured a relatively high

yield with low water consumption eroded and water waste increased drastically.
